EnableEmbeddedAsarIntegrityValidation instantly exits app - only on macOS

[Nantris]

Enabling the EnableEmbeddedAsarIntegrityValidation fuse leads to our app instantly exiting on macOS. On other platforms though, everything keeps working properly with it enabled.

I'm not sure if this means it breaks the macOS build, or if maybe it's not actually applied except on the macOS platform? Any thoughts?

Nobody else is seeing this? I'd really like to get this working!

Hi there, I'm not one of the Electron developers but I can say that this fuse currently does nothing on non-macOS platforms.

What library are you using to package your application? This fuse requires a specific set of hashes to be present in the ASAR bundle.

Thanks for your reply @complexspaces!

I noticed that while reviewing the docs today. Do you have further reading on the hashes you mentioned?

We're using Electron-Builder to package our app. I know 23.x.x is out, but we're still on the 22.x.x branch.

They linked a short document in the PR which added this fuse originally.

That would be your problem 😅. If you look at the official @electron/asar package, there is a module dedicated to generating these hashes. electron-builder, however, rolled their own ASAR creation code which doesn't have support for creating these hashes. You'd either need to patch/upstream an addition to electron-builder (or maybe switch them to the official package 🙈) or manually create the .asar bundle yourself.

Many thanks for the info @complexspaces!
